[0002] In recent years, with the gradual popularization of electric vehicles, the technical requirements for rapid replacement, rapid charging, battery safety and other aspects of electric vehicle batteries have gradually increased. At present, the common electric vehicle battery parts are completely placed in an independent storage space, and the temperature is monitored by induction sensing modules. Such structural design still has major deficiencies, such as poor heat dissipation performance. Although it can be effectively monitored, it cannot fundamentally improve the heat dissipation performance and reduce safety hazards. In the automated production process of square batteries, the fixture should also change with the length of the battery after the change of type. In order to facilitate the positioning of the battery without changing the fixture, it is necessary to position the battery from the length and width respectively and be able to extend into the fixture channel. However, the existing equipment cannot position the length and width of the battery, resulting in poor equipment adaptability and low formation efficiency. Summary of the invention
